Overview

The Global Modeling and Assimilation Office (GMAO) works to maximize the impact of satellite observations in climate, weather and atmospheric composition prediction using comprehensive global models and data assimilation. To achieve this goal, the GMAO develops models and assimilation systems, generates products to support NASA instrument teams and the NASA Earth science program, and undertakes scientific research to inform system development pathways.

Assimilation systems have been developed for the atmosphere, ocean, and land surface. GMAO's long-term goal is an integrated Earth system model and assimilation system that treats the individual components in a more coupled and interactive manner. GMAO works within numerous national and international collaborations to support its mission.
